12 Claims. 1`

This invention relates to new and useful im' provements in a typewriter for typing music.

More specifically, the present invention proposes the construction of a typewriter for typing complete musical scores including all the music symbols thereof, which symbols will be directly typed by manipulation of one of the type bars or by combining one or more of the type bars as will become apparent as this description proceeds.

Another object of this invention is to construct a typewriter having a flat platen for supporting a sheet of paper upon which a musical stai can be typed'and means for varying the relationship between the at platen and the type bars in a manner to permit the music symbols to be typed on vthe staff in their proper positions.

It is still another object of this invention to provide the typewriter with an auxiliary keyboard at the front of the normal keyboard, which controls the manipulation of the type bars, connected with the type bars in a manner to be used for shifting the type bars as a unit for varying their alignment with the flat platen.

A further object of the invention proposes arranging the keys of the auxiliary keyboard in banks of seven keys each comprising an octave of the musical scale in a manner to permit the desired key to be easily picked out by the operator of the typewriter to be depressed for typing a desired music symbol in a proper position on the musical stai.

`Still further the present invention proposes interposing a linkage system between the keys 'of the auxiliary keyboard and the basket of type bars which terminates in a bar extended beneath the keys of the auxiliary keyboard to be depressed in a manner to move the linkage and shift the basket of type barsv down a distance comparable with the distance the key of the auxiliary keyboard was moved.

Still another object of this invention proposes the provision of a novel lock arranged in connection with each of the keys of the auxiliary keyboard for engaging and holding the bar of the linkage system in a mannerto lock the linkage system to hold the basket of type bars from bouncing vertically during rapid manipulation of the typewriter causing music symbols to be typed in other than the desired positions.

Another object of the present invention proposes the provision of an adjustable stop for each, of the keys of the auxiliary keyboard which stops are individually adjustable in a manner to limit downward depression of the keys of s aid auxiliary keyboard to a desired amount.

The present invention also proposes the pro l vision of a novel means for holding the carriagecarrying the at platen back spaced one-half a space in a manner to leave the hands free to be used to manipulate the type bars or the keys ofstruction of a novel typewriter for typing musicwhich can be conveniently used for transposing music without the exercise of @any special skill on the part of the operator.

It is a further object of this invention to con-y struct a typewriter-for typing musical scores which is durable and simple in operation andk which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set' music constructed in accordance with the presentinvention.

The typewriter for typing music, according to the present invention, includes the usual typewriter frame 30 having the usual feet 3i for supporting the typewriter on a desk, table or other support. Mounted on the frame 3!) for lateral movement relative to the frame is the usual carriage 32. Details of the mounting of the carriage will not be given in this specification as they form no part of this invention and such details are generally known-to those versed inthe art. Y

The carriage 32 includes the usual paper rest 33 upon which the usual paper guide 34 is slidably mounted and against which the left-hand margin of a piece of paper is engaged for guiding the insertion of the. piece of paper into the carriage. platen mem-ber 35 preferably made. of Wood, metal or other similar material. A piece of ber material 36 is set into the front face of the platen 35 and is adapted to be engaged by the typing` heads of the typing keys. The hat platenv member 35 isy secured in positionon the paper rest 33 by means of screws 31, see Fig. 5, which pass through.

the paper rest 33 and threadedly engage complementary openings 36 formed in rearwardly extending side arms 39 of the iiatplaten member 35. The carriage supports a rod 40 which passes, through complementary bosses 4i formed Von the back face of flat platen 35. The side arms 39 Y of the flat platen 35 are arched to engage over the. ends of the rod 40. Atthe sides of the carria'ge 32, the rod 46 is formed with the usual knobs 42 which can be manually gripped for turning the rod. Fixedly mounted on the rod 40V between the bosses 4l of the flat platen 35 there are paper feed rollers 43. Cooperating with the paper feed rollers 43 are the usual idler rollers 44 and guides 45, see Fig. 4, for guiding a sheet of paper into typing position on the flatplaten 35. A U-shaped paper supportL member46 hasnits intermediate arm extended across the' face of the at platen 35 at the top thereofl and rested on short pegs 4l extending from the top corners of the :dat platen 35. The side arms of the the paper support member 46 extend rearwards and at their rear ends are pivotally attached to Attached to the paper rest 33 is a flat.

brackets 48 extending from a portion of the car'- riage 32. Springs 49 operate between the rearwardly extending arms of the paper support member 46 and a portion of the carriage 32 and urge the paper support member into contact with the short pegs lil on the front of the flat platen 35. The U-shaped paper support member 46 can be lifted against the action of the springs 49 to permit a piece of paper to be typed on to be engaged therebeneath to be supported in proper typing position.

Slida-bly mounted for vertical movement upon a xed portion of the frame 33 of the typewriter is the usual type bar support member 5B and supported thereon for pivotal movement in a substantially vertical plane are the usual type bars 5l, only one of which has been included in the schematic showing of Fig. 6. The manner of supporting` the frame 50 forI vertical movement is not shown in the accompanying drawings as such sliding movements are generally known to those skilled in the art, it being deemed suiicient to say that the'support 53 slides vertically; that is, vertically relative tothe fiat platen 35. The support 55 and the type bars 5I form what is generally known as a movable basket type typewriter construction.

Attached to the free ends of the type bars 5I there are typing heads 52, and these typing heads 52 are arranged to enter the usual V- shaped guide 53 which is associated with the usual typewriter ribbon 54, see Eig. 1, to type upon a sheet of paper supported on the flat platen 35. Linkages, not shown, are interposed between the type bars 5l and the usual typing keys 55. disposed to the front of the frame 38 of the typewriter. The typing heads 52 have embossed thereon the music symbols corresponding to those carried by the typing keys .55 shown on an enlarged scale in Fig. 2. Thus, as each of the typing keys 55 is depressed the symbol of that key will be typed on the piece of paper supported on the iiat platen 35.

Instead of the usual shift keys for :shifting the support member 53 vertically to Vary the alignment of the typing heads 52 with the fiat platen 35, an auxiliary keyboard 56 is provided at the front, of the machine and to the front of the typing keys 55. The auxiliary keyboard 5S comprises a number of shift keys 5? arranged in banks of seven keys each. Each bank of keys comprises an octave of the music scale, and while threeV banks are shown on the accompanying drawings it is pointed out that the keys may be arranged in banks of more or less number and still be operative for the intended purpose.

Each of the shift keys 5'! of the auxiliary keyboard 56 is mounted on the forward end of an arm 58'pivotally supported at its rear end upon a support rod 59 mounted upon a fixed portion of'tlie typewriter frame 33. Springs 65, see Fig. 7, operate between the arms 53 and a xed portion 6I of the typewriter frame 33 for holding the arms in their raised positions.

Means is provided for guiding vertical movement of the arms 58 as the shift keys 51 are depressed. In this connection, it will be noted from Figs. 1, 2 and 6 that the usual frame 62 which extends around the typing keys 55 has been cut away at the iront of the typewriter, providing an opening for the passage of the arms 58 of the auxiliary keyboard 56. Attached to the v ends of the forwardly projecting portions oi the frame 62, by means of screws 63, are dependthe depending blocks 64 is a plate 65. The plate 65 is secured in position by means of screws 66, see Fig. '1. Extended upwards from the bottom edge of the plate 65 there area plurality of slots 61. There is one slot 61 for each of the arms 58 of the auxiliary keyboard 56 and the arms 58 extend through the slots 61 as shown in Figs. 6 to 9 to have their vertical movements guided by the slots.

An adjustable stop 68 is provided for arresting the depression of each of the shift keys 51 of the auxiliary keyboard 56. To support the stops 68 a horizontal plate 69 is secured to the lower ends of the depending blocks 64 by means of'screws 18. Threadedly engaged through the back edge of the horizontal plate 68 there are a plurality of vertical stop screws 1I, one below each of the arms 58 of the auxiliary keyboard 56. These vertical stopwscrews 1| are in rear alignment with the slots 61 ofthe plate 65 through which the arms 58 extend. Set screws 12 are threadedly engaged in from the back edge of the plate 69 and are adapted to be tightened against the vertical stop screws 1| to hold them in desired adjusted positions. In Fig. 7 there is schematically shown the manner of adjusting the vertical stop screws 1| to limit the downward depression of the shift keys 51 to obtain the desired proper alignment of the typing heads with the lines of the conventional music staff.

Interposed between the arms 58 of the auxiliary keyboard 56 and the type bar support member 58 is a linkage system 13, see Fig. 6, for moving the type bar support member vertically as the shift keys 51 of the auxiliary keyboard 56 are depressed. The linkage system 13 is characterized by spaced bell crank levers 14 pivotally supported at the junction of their arms on bosses 15 by means of pins 15. The bosses project towards each other from a xed portion of the typewriter frame 38. The horizontal arms 11 of the bell crank levers extend along the sides of the group of arms 58 of the auxiliary keyboard 56. A bar 18 is supported between the free ends of the horizontal arms 11 of the bell crank levers 14. The bar 18 extends beneath the arms 58 and is in contact with the bottoni edges of those arms, as shown in Fig. 8. Thus, when one of the shift keys 51 is depressed its respective arm 58 will be correspondingly moved until downward motion is arrested by engagement of the bottom edge of the arm 58 with the top end of the vertical stop screw 1| of the respective arm 58 which has been depressed. Since the bottom edge of that deedly mounted at their bottom ends upon thel shaft 8| and have their upper ends connected to the rear ends of the rearwardly extending connecting members 88. Also f'lxedly mounted on the shaft 8|, inwards of the substantially vertically extending arms 82, is a second pair of substantially horizontally extending arms 83. The free ends of the horizontally extending arms 83 are in turn connected by means of vertically extending connecting rods 84 to .the type bar support member 58. When the bell cranksd are pivoted as hereinbefore described, the bell cranks will draw on the connecting members and the substantially vertically extending arms 82 to turn the shaft'l and cor` respondingly turn the substantially horizontally extending'arms 83 in a downward.. direction to pull downwards on the connecting rods 84 and move the support member 58 and type bars 5| downwards a distance corresponding to the distance the arm 58 of the auxiliary keyboard 56 was depressed before its downward motion was arrested by its engagement with its respective vertical stop screw 1|. The support member 50 is connected with its usual means for again lifting it and restoring the linkage system 13 to its starting position when the pressure on the keys 51 is relieved. The arms 58 will be restored to their starting positions by their respective springs 66, see Fig. 7.

As the type basket comprising the support 58 and the type bars 5| is rather heavy, the type basket displays a tendency to bounce vertically relative to its guides when the machine, and particularly the shift keys are manipulated rather rapidly. If a type key 55 should `be depressed while the type basketis bouncing vertically,.the tendency is for the musical symbol to be typed in a position other than the correct position for the particular shift key which has been depressed. 'Io eliminate this objectionable bouncing of the type basket, a lock is provided for gripping and holding the bar 18 of the linkage system 13 in the full depressed position of the particular shift key which has been depressed. This lock comprises a lock lever 85 for each of the arms 58 of the auxiliary keyboard, and each lock lever 85 is pivotally attached to its respective arm 58 by means of a pin 86 and the lock levers 85 depend freely downwards and rest on the top ends of the respective vertical stop screws 1l of the arms 58. The lock levers 85 also have depending,

. appreciated that the lock levers will extend downwards at different angular positions depending upon the adjustment of the stop screws 1| of the respective arms 58 to which the lock levers 85 are pivotally attached.

The inoperative position of the lock levers 85 is shown in Fig. 8 of the drawings; however, when one of the shift keys 51 is depressed its respective arm 58 will move downwards moving the bar 18 downwards also. The respective lock lever 85 will not move downwards because of its engagement with the top end of the respective stop screw 1|, as shown in Fig. 8. Dcwnward movement of the arm `58 will fulcrum the lock lever 85 about its pivot pin 86 and its point of engagement with the top of the stop screw 1| and project its tail portion 81 upwards and'rearwards to engage substantially beneath the bottom of the bar 18, as shown in Fig, 9. This will cause the bar 18 to be'gripped between the adjacent edges of the arm 58 and the lock lever 85 and hold the lock lever and in turn the support member 58 and type bars 5| against bouncing as previously described.

The typewriter has the usual mechanism controlled Vby the movement of the type keys 55 for advancing the carriage 32 one space to the left each time one of the type bars 5| is pivoted to cause its respective type head 52 to strike the flat platen Y35. However, in using the present typewriter to type musical scores it is sometimes necessary to strike two or more type keys 55 in the same space to form a desired music symbol, and then it is necessary that the carriage not move between these strikings. Accordingly, the machine is provided with mechanism for rendering the carriage moving mechanism inoperative Awhen desired. The type keys 55 include the usual space bar 88 at the front of the machine, connected with the usual mechanism for advancing the carriage 32 one space to the left without the necessity of striking one of the type keys 55. The operation of the space bar 88 is not affected by the mechanism of the present machine which renders inoperative the spacing mechanism controlled by the type keys 55 for moving the carriage to the left.

.Details of the spacingr mechanism controlled by the type keys 55 and the mechanism of the present typewriter for rendering the spacing mechanism inoperative are shown in Figs. 13 to 17. The. spacing mechanism is shown somewhat schematically, as such spacing mechanisms are common in the eld of typewriter construction. The spacing mechanism includes a rack 89 (shown in dot and dash lines in Fig. 14) attached to the carriage 32 and extended from side'to side of the typewriter. A pivctally mounted dog 90 has its upper end engaging the teeth of the rack 89 and is urged into an operative position by means of a spring 9|. The dog S0 also controls the usual escapement m-echanism, not shown, for insuring that the carriage will be advanced one tooth of the rack 89 each time the dog 80 is pivoted to disengage the rack B9. The lower end of the dog 90 carries an adjustment screw 92 for adjusting the sensitivity of the dog 90 and its escapement mechanism.

Depending arms 03 are attached pivotally at their upper ends by means oi pins 94 to brackets 95 extending from fixed portionsfof the typewriter irame 30. vertically spaced horizontal rods 98 and 91 are extended between the depending arms 93. Hook members S8 extend from the linkages (not shown) which connect the type bars 5| with the type keys'55 and extend overthe bottom horizontal rod 9i as shown in Figs. 13 and 14 for pulling on the bottom horizontal rod 91 and pivoting the depending arms 93 each time e one of the type keys 55 is depressed. Fixed to the top horizontal rod s6 in alignment with the dog 90. is a depending lever 99. Pivotally attached to the lowerend of the depending lever -99 is an extension member |90. The depending lever S9 and .the adjacent end of the extension member |00 are pivotally connected together by means' of a pin |0I. Thus, when the dependingarms 93 are pivoted forward by one of the hook members 98, the extension member i00 will also be moved forward to strike the adjustment screw S2 and pivot the dog Si? against the action of the spring Si and move the top end of the dog Sii to disengage the rackv 89 and free the carriage 32 to move one space to the left.

Mechanism is provided for pivoting therextension member |00 from the full line operative position shown in Fig. l5 to the det and dash line inoperative position shown inthat figure. In the inoperative position the extension membei' |00- will be outof direct line `with the adjust'v ment screw 92 thus preventing the extension member from engaging the adjustmentscrew 92 when the arms 93 are pivoted forward by the hook membersQS. The mechanism for pivoting the extensionmember H30 comprises a connecting link |02 attached at one end to the bottom end of the extension member |00 and extended to one side of the frame 30 of the machine. The other end of the connecting link |62 is-connected to one arm oia bell crank lever |03 pivotally attached by means of a pin i524 to a bracket |05 extending from a xed portion of the typewriter frame 30. Theother-arm of the bell crank lever |03 is connected to a forwardly extending connecting link |05, which is in turn connected to an arm |01. The arm |07 is fixedly attached to the lower 4end of a'vertical pin |68 which is rotatively supported at its lower end in a bracket |09 attached to the frame 30 of the typewriter. Fixedly mounted on the pin |08 above the arm |01 isa control arm iii) which extends through a slot formed in the front wall of the frame 30 of the typewriter. The projected end of the control` arm H0 is formed with a knob H2 which can be manually gripped for moving the control arm He from one end to the other of the'slot I||. Such movement of the control arm H0 through the medium of the intervening linkage shown in Figs. 13 to 17 will move the extension member |00 between the operative and inoperative positions shown in Fig. l5.

Means is provided in connection with the pin |08 to hold the control arm ili! in position at either end of the slot i i to correspondingly hold the extension member |i0 in either an operative or inoperative position. This means comprises a cam llifixedly mounted on the top end of the pin |08 and provided with a pair of cam notches H4. A roller H5 is engageable with either of the cam notches I4 and is rotatively supported on one end of -a lever H6. The opposite end of the lever Ii is pivotally mounted on a fixed bracket il'i'by means of a pin H8. A spring ||9 operates between. an intermediate portion of the lever i i6 and a xed lug 20 for urging the lever H6 into a position in which its roller willengage the edge'of the cam H3 and more particularly retain the roller H5 in engagement with one of the cam notches ii. When the control arm ||.0 is at one end of the slot IH, the roller H5 will engage in one of the cam notches |11 and when the control arm HE is at the other end of the slot the roller H5 will engage the other of the cam notches i i4.

The typewriter also has the usual baci; space key |2|, see Figs. l, 2 and 10 to 12, associatediwith the usual mechanism for causing the carriage 32 to be back spaced one space each time the-back space key |2| is depressed. In typing music with the present typewriter it is sometimes necessary to back the carriage up one-half space in order to form a desired musical symbol, as will become apparent as this description proceeds. Ordinarily this is done by holding the back space key |2| partially depressed while striking the desired type key with a nger of the free hand. However, as both hands are required for theoperation of the present typewriter, one for depressing the desired type key 55 while the other holds the desired shift key 5l of the auxiliary keyboard 56 in a depressed position, it is necessary that some means be provided for holding the back space key |2| in its partially depressed positionto holdthe carriage 32 spaced back onepivoting. =with a cam cutout/|28 into which a pin |29 of a lever |30 isA adapted to be engaged as shown in 9. half space. 'A novel lock |22, illustrated in detail in Figs. to 12, is provided for this purpose.

The lock |22 comprises a holding element |23 *which is pivotally supported by means of a pin |24 upon a boss |25 which projects from lthe frame 62. vrearwardly extending arm |26 of the hold'ng ele- In its forwardly pivoted position a ment |23 is adapted to engage a stud |21 projecting from the frame 62 and limit forward The. holding element |23 is formed Fig. 12. The lever has a pivotal attachment fat. a point, not'shown, which is concentric with "the point of pivoting of the rearwardly extending armi-'5| of the-back space key |2|. It is the arm |3| that is connected tothe back space .mechanism of the typewriter which is not shown vvon the drawings. The'lever |30 andthe arm ISI "are connected together forunitary movement by 'means of a length of stiff wire |32.

when the pin |29 enters the cam cutout |28 as shown in Fig. l12V it will be disposed beneath a bulge |33 von the forward wall defining the cam cutout |28 so as to hold the pin |20 in position in the cam cutout |26.

To hold the back space key |2| inthe half back space position, the back space key is depressed with one hand while simultaneously pivoting the holding element |23 rearwards about its pivot pin |24 causing the pin E29 to enter the cam cutout |28 and be simultaneously engaged :beneath the bulge |33. When the pin reaches the l bottom end of the cam cutout the carriage will be back spaced one-half space and will be rey,.tained in this position by reason of the engagement of the pin |29 beneath the bulge |33. This formed with the arm |3| to move vertically therewith.

All of the mechanical features of the typewriter of the present invention for typing musical v scores have now been described and the following .is a description of the. method used .for typing the present type' several musical symbols with writer: n

Figs. 18 to 23 illustrate the principles involved in typing music with the. present invention.

Referring first to Fig. 18, this gure illustrates theV manner of forming the various musical symthe top or F line of the normal music scale.

'machine, the like keys of each bank have been marked for identification purposes with the additions of primes in the twovlower banks; as for example, F, F', and F, and so on.

There are certain musical symbols which achieve no particular significance from their position on the music scale and those symbols 'when typed with the F shift key 51a depressed will appear in their normal position on the normal music scale. This is illustrated, for example, at the left of Fig. 18 where the treble clef, con'- trolled by the type key the bass clef, convtrolled by the type key 55; and the vertical line controlled by the type key 55d are shown in their normal positions on the music scale-both .the scale and the symbols having been typed withl the F shift key 51er ofthe auxiliary keyboard 56 depressed.

There are other music symbols which achieve special significance from theirposition `on "the music scale and those symbols when typed with the F shift key 51a depressed will be typed on ThiS is illustrated for example at the right of Fig. 18, where the quarter note with the tail down, controlled by the type key 55; the quarter note with the tail up, controlled by the type'key 55f; the whole note, controlled by the type key 558; the half note with the tail down, contro'led by the type key 55h; the natural, controlled by the type key 551; the sharp, controlled by the type key 551; andthe flat, `controlled by the type key 55k are shown typed'in position on the top or F line'of the music scale-and again, both the scaleand music symbols have been typed with the F shift key 5'!a of the auxiliary keyboard 56 depressed.

' In Fig. 19, there is illustrated a quarter note typed in the high C position with relation to the normal scale with the additional lines typed above the normal scale to position the quarter note. As previously described, the normal scale is typed with the type key 55a and withthe'F shift key 5'|a of the auxiliary keyboard 56 held in a depressed position. The quarter note in the high C position is typed with the type key 55e and with the high C shift key 5`|c of the auxiliary keyboard depressed. The extension of the scale above the normal scale is obtained by using the type key 55a, which was used to type the scale in the normal position, but this time bols on the typing heads 52 of the type .bars 5|.

The typing key 55a, see Fig. 2 controls a type bar 5| which has a type head 52 provided with five vertically spaced short horizontal lines, and when the key 55a is successively depressed with the shift key 57a of the` auxiliary keyboard 5 6 n held in a depressed position, a normal music scale 4will be typed on a sheet of paper supported on the flat platen 35. The shift key 5`|a corresponds to F of the Ymusic scale; thatis, theF above fmiddle C, which is the shift key 5'!b of the auxiliary keyboard 56,`and which key 'is marked C'in Fig. 1. i As each bank o'fkeys in Fig. 1 form with the high C shift key 51 depressed, instead of the F shift key 51a. This will print the scale segment with two'lines extended above the nor- Ymal scale and with the three lower lines overv'lapping the top three lines of the normal scale 'as indicated by the darkened areas in Fig. v-19.

As it is' necessary that both thequarter note andthe extension of the scale be typed in the vsame' space, to produce'the nished arrangement shown at the left of Fig. 19, the knob y|12 `isA moved to the right side of the slot see Figs. 13 and 17, to move the extension member |00 to the dot and dash line position shown-in Fig.' 15 to prevent the carriage from being moved `one'fspace to the .left between 'depressions of the keys 55e and 55a. After depression of the key 55e, the knob ||2 may'again be moved to 'the left of the slot so that when-the key 55a is depressed the carriage will be'spacedpne 'V space to the left, so that the next music symbol ,will not be'typed over the one just completed.

a complete octave and as the banks are one octave lower from the back to the lOlt -Qf @1113' lAs this description continues, it is to be under- Stood that the term normal scale means the Scale that will be obtainedby typing with the armadas l1 :type keyafandjwith theyFshit key leoif. the auxiliary keyboard, Sfr, held; in. a depressed; iposition..

Theioregoing,description. oi forming the. varions. notes inthe. various positions on theimu's'ical scale. is-,by wayofA illustration only, andlit is` appreciatedthat the. position oi thev-arious. notes on the. soalemay beichanged by usingother shift `keys of theauxiliary.keyboard' and/that other .musical symbols in desired. positions. onthe musiltal scale can beformed by using other combinations-of type-keys and shiftfkeys.

The typewriter in accordance with the present invention may also be conveniently used for transposing music without the exercise of any vspecial skill on the part of the.A operator.. This can-bef easily accomplished by .typing the-scale .in the key in` which it is desired. to transpose the music and then typing the notes'in the key in which the sheet of music was Written land :they will appear in their-proper. position-onthe transposed scale.
